Clinically, many patients with a clear diagnosis of lumbar disc herniation, spinal stenosis, and lumbar spondylolisthesis should have opted for surgery, but continued to suffer from the disease because of the fear of surgery, and some even caused sequelae such as lower limb numbness, muscle atrophy, weakness, and claudication. The reason for this is mainly due to the lack of understanding of the surgery. Here, I will make a brief introduction of the post-admission process to eliminate the fear or worry about the surgery and its risks and pain. Pre-operative examination items after admission: blood (including blood routine, clotting time, liver and kidney function, etc.), electrocardiogram, full chest X-ray, and cardiac ultrasound and pulmonary function measurement will be checked in elderly patients or patients with heart and lung dysfunction. One day before surgery, a consent form for surgery will be signed, and there may be skin test and blood type matching (blood preparation). You can eat and drink normally at night, but no food is allowed after 12:00 pm at night. Enemas are sometimes needed at night. You can take a bath at night, but avoid getting cold. If you do not sleep well, you can take a sleeping pill temporarily to ensure sufficient sleep. On the day of surgery, change into a hospital gown and wait for the operating room trolley to pick you up. At present, the main choice of lumbar spine surgery is general anesthesia, the safety of these drugs is very good and easy to control, coupled with the current advances in technology, real-time monitoring of heart and lung function and bleeding during surgery, its safety is very high (foreign countries generally choose general anesthesia), but also to avoid a variety of adverse stimuli, eliminating the fear of surgery. The specific process: the nurse will first infuse fluids, then the anesthesiologist will put a mask-like thing on, and after that, sleep. Most tertiary care hospitals are experienced due to the large volume of surgery, and there are generally no cases of paralysis in lumbar spine surgery. The operating rooms are equipped with laminar flow equipment, which allows for an environment with almost no bacteria in the air and a good level of safety. When you wake up, you are usually in the resuscitation room, and then you will hear the nurse say loudly: move your feet and legs, which means you should have woken up and the operation has been successfully completed. When you return to the ward, the doctor and nurse will move you back to the bed and connect you to the monitor. As the wound has been treated with analgesia, or sometimes with analgesic pumps, you will not feel too much pain in the wound, but if the pain is more obvious, you can get a temporary pain injection, which will not affect the wound healing or your body. After fully awakening, you can turn over and drink some thin porridge and rice soup, and if there is no abnormal reaction, you can eat normally. On the day of surgery, you can go to the toilet and walk around the room (you need to wear a waist brace). After surgery, there is usually a significant relief of the original pain before surgery (some patients complained “finally slept well” on the second day after surgery), but because the nerves are more delicate, sometimes even if the compression has been lifted, the original nerve indentation will lead to temporary numbness in the original pain area, which will generally gradually reduce in degree and scope. After the operation, the infusion is usually given for 3~5 days, and if there is no obvious abnormality in the wound, the patient can be discharged home to recuperate. The stitches are usually removed 10~14 days after surgery, and the bath is taken in about 3 weeks.
